Answer:
Money is not the only "thing of value" that you need to be concerned about. RESPA Section 8 prohibits giving or receiving ANYTHING of value in exchange for the referral of settlement service. They may be wanting you to list them as a preferred lender on your website - that is a thing of value. There could be any number of other "things of value" that they may be seeking or offering in this relationship. Seek legal counsel before entering into any type of partnership relationship with a lender.
